Although the diameter won't affect anything, the rotor thickness creates a fitment issue. However, 81-87 1/2 ton trucks were available in both 1" and "heavy duty" 1.25" rotors. As cheap as calipers are, it's worth a shot to try, but keep in mind the 81-87 calipers are metric, so the banjo fittings are different.

Thanks Matt, appreicate the info...Jim
